Kern Ultrasound Hardness Testing Device HO
Kern Ultrasound hardness testing device is ideally suited for mobile hardness testing, where the main emphasis is on obtaining rapid and precise results. The SAUTER HO measures using a Vickers Diamond tip, which is pressed into the test piece with a defined force. After that the tip is moved into high-frequency ultrasound vibrations, the hardness is derived from the attenuation. Ideal for measuring small forgings, castings, welding points, punched parts, casting tools, ball bearings, flanks of gear wheels and for measuring the influence of warmth or heat.
Features and Benefits
Advantages compared with Rockwell and Brinell: Less test force and therefore only microscopic, small penetrations means that the testing is less destructive
Advantages compared with Vickers: Demanding optical measuring is not required. You can therefore carry out measurements directly on-site, for example, on a permanently installed workpiece
Advantages compared with Leeb: The high requirements for the weight of the test object are no longer required
Mini Statistics Function: Display of the measuring result, the number of measurements, the maximum and minimum value as well as the average value and the standard deviation
Measurement data memory saves up to 1000 measurement groups each with 20 individual values
Calibration: The device can be adjusted to standard hardness comparison plates and to individual reference standards
Standards
